Embodiment
Below, with reference to accompanying drawing suitable embodiment of the present invention is at length described.
[resin]
Can be used in the resin of translucent resin body material of the present invention, so long as can be by carrying out injection-molded moulding in the inner chamber in metal pattern after the melting the outstanding resin of shaping translucent resin body material and light transmission, then its material is not particularly limited.Also can use diethylene glycol bis-allyl carbonate (CR-39), polymethylmethacrylate (PMMA), methyl methacrylate (MMA) etc., but the present invention especially is fit to use the resin of melting under the high temperature more than 250 ℃.As its typical example, can enumerate polycarbonate (PC).
In the following description, describe as an example of polycarbonate example.
[phthalocyanine is pigment]
Phthalocyanine is that pigment is well-known as near infrared absorbing coloring matter, and the situation that the extreme value of its absorbing wavelength changes according to the difference of molecular structure is also by cognition.Therefore, as shown in Figure 1, according to purposes and the different various phthalocyanines of the extreme value of absorbing wavelength are that pigment is sold on market.
Be an example of pigment as the phthalocyanine of selling on the market, can use " Excolor " (イ one エ Network ス カ ラ one, registered trademark) of Nippon Shokubai Co., Ltd (Nippon Shokubai Co., Ltd.) system.
Above-mentioned phthalocyanine is pigment, can dissolve as solvent with butanone or 2-butane, toluene etc., and can under this is dissolved in state in the solvent, analyze absorption spectrum, Fig. 1 and Fig. 2 are the absorption spectrums when mixed dissolution has the different various phthalocyanines of molecular structure of 5% (weight percent) to be pigment in toluene solvant.
The phthalocyanine that can be used among the present invention is pigment, is to have transmitance less than the minimizing pigment of 10% spectral transmittance curve in the wave band as the 800nm～1000nm of target.
Be that the example of pigment exemplifies in Fig. 1 and Fig. 2 with such phthalocyanine.
The phthalocyanine of Fig. 1 (a) to be pigment have before and after 820nm transmitance is less than 10% extreme value, the phthalocyanine of Fig. 1 (b) to be pigment have before and after 850nm transmitance is less than 10% extreme value, and the phthalocyanine of Fig. 1 (c) is that pigment has transmitance less than 10% extreme value before and after 880nm.In addition, the phthalocyanine of Fig. 2 (a) to be pigment have before and after 970nm transmitance is less than 10% extreme value, and the phthalocyanine of Fig. 2 (b) is that pigment has transmitance less than 10% extreme value before and after 980nm.
[phthalocyanine is the decision of the combined amount of pigment]
To make such various phthalocyanines illustrated in figures 1 and 2 be two or more pigment in the pigment, that have different extreme values respectively with the weight range melting of 1ppm～500ppm the time, in the polycarbonate that has been mixed in 250 ℃～300 ℃ of lower meltings.If less than 1ppm, then almost can not manifest infrared absorption effect, if surpass 500ppm, then can visible light also interdict and can't bring into play effect as sun glasses.The lower value of the transmitance that allows in visible region (wave band of general 500nm～700nm) is approximately about 15%.
As the example of combination, for example can enumerate and have transmitance before and after the 820nm and be pigment, be pigment and to have transmitance before and after 880nm be pigment less than the phthalocyanine of Fig. 1 (c) of 10% extreme value having the phthalocyanine of transmitance less than Fig. 2 (a) of 10% extreme value or Fig. 2 (b) before and after the 980nm less than the phthalocyanine of Fig. 1 (a) of 10% extreme value.
The standard of the amount of mixing can obtain from the variation of the transmitance of visible region being guaranteed the spectral transmittance curve under the state more than 15% by experiment.For example, suppose that the multiple phthalocyanine that structure is different is pigment and suitably mixes the spectral transmittance curve of the transmitted spectrum of the translucent resin body material that (for example respectively as 150ppm) obtain take the weight range of 1ppm～500ppm, be curve as shown in Figure 3.In this transmitted spectrum, till near as the 800nm to 880nm of target and show strong infrared ray absorption ability less than 5% near the 970nm, but, because the place has the crest about 10% before and after 900nm, and the spectral transmittance curve transfers rapid rising near the 970nm, and is therefore in wave shape as a whole.
Therefore, under these circumstances, to be that pigment and near the phthalocyanine that has extreme value 970nm are pigment near the phthalocyanine that has extreme value the 900nm, in its gross weight is the weight range of 1ppm～500ppm, append in right amount respectively or increase, and the translucent resin body material that obtains obtained transmitted spectrum, thereby analyze the spectral transmittance curve.Determine that from such repetition best phthalocyanine is combination and the amount of pigment.In addition, in general, because phthalocyanine is that pigment is very expensive, therefore, with after the spectral transmittance curve that reaches as target, to be that the amount etc. of pigment obtains being combined as of least cost good by reducing lentamente employed phthalocyanine.
[melting, injection]
In the polycarbonate that will be mixed in 250 ℃～300 ℃ of lower meltings by the combination that is pigment of the above-mentioned phthalocyanine that determines and amount, and this blend melt (Melt) is injected in the inner chamber of metal pattern.By like this, obtain the spectral transmittance curve and in the wave band of 800nm～1000nm, have transmitance less than the translucent resin body material of 5% smooth mnm. band.This translucent resin body material, can be used as eyeglass or spectral filter etc. opticinstrument material and use, and be pre-formed size and shape into for example ophthalmic lens by the shape with above-mentioned inner chamber, can when obtaining the translucent resin body material, obtain the outstanding ophthalmic lens of infrared ray-absorbable.
[additional function]
In translucent resin body material of the present invention, also can add polarisation function or dimming function, vision correction function.In addition, except phthalocyanine is pigment, also can add as required other pigment or additive.
